This kit has four buttons and LEDs to make up a game, which can be used as both a memory game and a reactions game. A PIC micro-controller, pre-programmed with special software controls the game. The on / off switch and battery pack mount directly onto the board allowing it to be used as built or alternatively it can be housed into an enclosure of your own design.1 x 2x AA PCB Mount6 x 680R Resistor1 x 47R Resistor1 x Red 5mm Diffused LED - 275mCd1 x Green 5mm Diffused LED - 35mCd1 x Yellow 5mm Diffused LED - 125mCd1 x Orange 5mm Diffused LED - 275mCd4 x 6mm PCB Mount Tactile Switch, 9.5mm height1 x IC Socket 8 Pin1 x PCB Mount Slide Switch1 x Pan Head M3 x10mm Machine Screw1 x M3 Hex Full Width Nut, Zinc1 x Electronic Game Kit PCB1 x Pre-Programmed ICFootnotesRequires; 2x AA Batteries, Soldering Iron, Solder, Wire cutters and screwdriver
